1999 Pontiac Grand Am 6 cyl Front Wheel Drive Automatic 185000 miles

Where is the crankshaft position sensor on my 99 grand am and how do I know if it has a lead wire or not because auto zone said there is a 15 dollar difference in the part if there is a lead wire or not.

Your vehicle has 2 crankshaft sensors. The 7x CKP sensor runs to the ignition control module and the 24x CKP sensor leads to the main computer. The 24x CKP is the one with a lead wire so you will have to look over the diagram to point out which sensor you are needing replaced..
